Well, it looks like it took 1 in this case or it involves-- we can put it another way, merging those two lists involved looking at two numbers, 1, 2, and that's it.
在这种情况下看起来只用了1次-,我们可以从另一个角度看,合并这两个列表涉及到了,2个数字,1,2,就是这样。
Actually it's not 40, I think these are, 75 alright. So the answer is 75 and the number of calls is 1.7 million.
实际上不是4,我觉得,好了,所以答案是5,调用次数是1百70万次。
So I can go from 8 to 4 to 2 to 1, so that's 3.
我可以从8到4,到2,再到1,所以是3次。
